The only answer chose that can not be increase is B. Seasons, there are set days for the beginning and ending of each season that does not change.
All the others can be increased.
Hope this helps you. :-)
b. How could seasons increase? That doesn't make any sense.
The correct answer is B. Seasons, as they do not change in number or duration. All the other options (weight, rainfall, and allowance) can increase depending on various factors. Seasons are fixed periods and therefore cannot increase.
